Hello,
From your description of the other body parts jerking in the past and now the mouth becoming involved you may wish to get some
genetic testing done to discover whether or not you have a
mutation in the DYT1 gene complex.
No particular medication does better than any other except for
BOTOX which improves symptoms of
dystonia in about 70% of patients properly injected.
Homeopathic treatment is unlikely to help with this problem.
Unfortunately CURABLE is not the right term to use for this condition since we don't fully understand what causes it in the first place but it is something that can be managed.
However, each patient's plan is customizable to the exact type of dystonia they have and whether or parts of the body are involved or not.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Dariush Saghafi, Neurologist
